* fix failure to distinguish input/match failure in wide %[ scanfRich Felker2012-04-171-1/+1
| | | | | this also includes a related fix for vswscanf's read function, which was returning a spurious (uninitialized) character for empty strings.
* introduce new wide scanf code and remove the last remnants of old scanfRich Felker2012-04-171-12/+28
| | | | | | | | | at this point, strto* and all scanf family functions are using the new unified integer and floating point parser/converter code. the wide scanf is largely a wrapper for ordinary byte-based scanf; since numbers can only contain ascii characters, only strings need to be handled specially.
* initial check-in, version 0.5.0 v0.5.0Rich Felker2011-02-121-0/+19
